Unable to unlock TrueNAS Scale dataset with correct passphrase

TrueNAS General
1

I’m currently using TrueNAS SCALE, version 22.12.3.3.

  • Pool: Unencrypted
  • Dataset: Encrypted using a passphrase

Issue:
After rebooting TrueNAS, I attempted to unlock the encrypted dataset using the correct passphrase. However, it fails to unlock and displays the following error:
“Provided key is invalid.”

Could you please suggest possible solutions or steps to unlock the dataset?

Thanks.

I understand this is a frustrating situation, and we have lot less info here to work with. Still let’s try to take a second look at this to avoid some possible gotchas here:

  • You mentioned ‘after reboot’. So first, please try with your caps on the keyboard set to on. We never know if they were on/off while you were setting the password before reboot.
  • Similarly, if you happen to have a second/alternate keyboard layout on the client system used for setting the password - that may be tried with all the possible combinations.
  • Next, there could be a possibility that there was some key that failed on a keyboard. I have see this happen especially with laptops (it could be even the shift key, Fn key etc.). So try through these possibilities as well.
  • Finally you could try attaching another keyboard and try the luck.

Hope this helps.
